CO2 is the chemical shorthand for which compound?

Understanding chemical formulas helps read shorthand like CO2. It shows one carbon atom (C) and two oxygen atoms (O2); the subscript 2 after O indicates there are two oxygens. This combination is carbon dioxide. For contrast, CO would be carbon monoxide (one carbon and one oxygen), O2 is oxygen gas (two oxygens), and N2 is nitrogen gas.
